Be it known tliatl, JAiins'fvDioiisoN'. LAinLAw, a subject of the King ofthe' United Kingdom of Great Britain'and Ireland, and resident of 44 Bernard Street, Leith, Edinburgh, Scotland, have invented certain new and useful Improvements in Machines for Cutting or Breaking Down htlasses of Pulverulent Material, such as Ai'- tificial Manni-e, of which the following is a specification. f

This invention relates to a machine or apparatus for cutting, grinding or similarly breaking-down large masses of material, such as pulverulent material which may set. hard with storage as in the case of artificial manure. The machine is however equally applicable to the cutting, grinding oi reducing of large masses of -other substances either of a pulverulent or solid nature.

The machine or apparatus consists 0f a revolving cutter, grinder or like revolving tool which is moved along the face of the material or substantially parallel to the face thereof. i

In the preferred construction of machine according to this invention, the rotary cutter or rotary tool projects laterally from a supporting framework and is rotated by gearing which may also be adapted to effect the traverse of the tool. The supporting framework and gearing may vbe mounted upon Aa carriage or otherwise portably mounted so as to facilitate feeding the tool towards the face 0f the material to be cut.

A machine suitable for reducing large masses of artificial manure is illustrated by way of example on the accompanying drawings whereon z- F ig. 1 is a side View of the machine and Fig. 2 is a face view thereof.

In the construction illustrated, a rotary cutter 3 projects laterally from a framework 4 which is mounted on wheels 5. rThe framework 4 may be either vertically, disposed Y (as shown on the drawing) or it may be arranged either horizontal or otherwise according to the material to be operated on. On the drawings the spindle 6 of the cutter 3 projects horizontally from one side of the framework 4, but the cutter 3 may be arranged within tlie framework so as to protrude slightly therefrom.

Any suitable form of gearing may be provided for rotating the cutter 3 and for trav- 7, 1922i 'seriali4 586,62;

In thegexamplexillustrated they tool spindleV 61s monete-duren@ S1`d'ev7 mevable alors guide bars or supports 8,whifeli areslmwn of channel-section. The slide 7 may betraversed along the guide bars 8 by means'of a.'

wincli9 controlling a rope or cable 10 which is wound thereon and passes around a pulley 11 supported by the framework 4, the other end of the rope 10 being attached to the slide 7. In the construction illustrated, the slide 7 is raised by means of the winch 9 and falls by gravitation, the winch 9 having a clutch 12 and a clutch lever 13,v

clamped to a longitudinal rod 14 sliding through fixed guides. The rod 14 carriesa tappet 15 adapted to be struck by the slide 7 a belt or cord from a'pulley 17 which turns c with a belt pulley 18 around which-,passes an endless belt 19. The belt 19 is driven by a belt pulley 20 and one side of the belt passes over a pulley 21 on the tool axle and around a jockey pulley 22 which travels with the slide 7 The belt pulley 20 is driven by gearing 23 from an electric motor or other prime mover 24 mounted on the framework 4. The cutter 3 is thus rotated whilstv the slide 7 traverses along thefraiework.

In the construction illustrated, the tool lspindle 6 is coupled to one end of a shaft 25 molunted in bearings 26 inthe slide 7 and carrying the belt pulley 21 thereon.

at each end of the shaft 25,sov that 4the cutter 3 may be arranged at either side of theV framework 4 according to requirements.V

A conveyor or elevating device maybe @provided for receiving the material loosened As i shown, a coupling flange 27 may be provided portof the material. The. conveyor. or elevating device may be mounted on the framework 4 (preferably beneaththe cutter l,

and may be driven from the motor 24.

Claims:

i. A machina of the kind as described' comprising a portable frame, a substantially vertical track onsaid frame, a slide for traversing said track, a rotary. tool Journaled in said-slide, a drive pulley on said tool,

l A Meana-g an idler ipulley journaled in said slide and operatively aligned with said drive pulley, an endless belt for driving said pulleys, said belt running on fixed pulleys disposed at either end of said track, and means for traversing said slide along said track comprising a Winchfor hoisting said slide, and gravitational means for returning it.

2. ik machine of the kind asdescribed comprising a portable frame, a, substantially vertical track on said frame, a slide for traversing said track, a rotary tool journaled in said slide, a drive pulley on said tool, anidlerpulley journaled in said slide and operatively aligned With said drive pulley, an endless belt for driving said pulleys, said belt running on fixed pulleys disposed at tomatically controlled by said slide at itsV travel limit, and gravitational means for returning said slide. The foregoing specification signed at Edinburgh, Scotland, `this tWenty-irst day of August, 1922.
